One is by finding the spot midway between the testicles and anus. There is a small indentation about the size of a pea or maybe larger. Be gentle and push inward. He will feel the pressure deep inside and it may be intensely painful at first. Eventually, as this area is worked on and softened, he will be able to expand his orgasms and master ejaculatory control. You can massage his Lingam with your right hand and massage his Sacred Spot with your left hand. Try pushing in on this spot when he nears ejaculation. It is aptly named the Million Dollar Point in Taoism.
The other way to access the Sacred Spot is through the anus. Many men, especially heterosexual men, are uncomfortable at first as a result of negative sexual conditioning. Be careful here and use lubrication. The key is to go slow and be very gentle. Make sure he is breathing as you slip a finger from your left hand into the anus about an inch or so. Then crook the finger back in a "come here" gesture. You will feel the prostate gland. Vary the pressure and speed of massage. He may want stimulation of the Lingam as you massage the Sacred Spot. Back off on the Lingam as he approaches orgasm and increase the pressure on the Sacred Spot.
Sometimes the man may have strong emotions come up during access to
the Sacred Spot. He may cry and remember a traumatic event from his past.
You, the giver, are in a place of trust and intimacy. Allow him to feel
his emotions and be very loving, not trying to console or fix him, just
let him feel whatever he needs to. Encourage him to scream, cry, moan,
sob, if it feels appropriate. Be the best friend and healer he could have
in that moment.
